Fig. 7,.is av vertical section on line .22.of Fig. 6. Fig. 8 is a fragmentary perspective view showing tumbler operating hooks and means'for engaging and disengag- Qin'g :the same, together with. surrounding mechanism. Fig. 9 is a section through Fig. Sapproximately on line 9-9, the same having shown in connection therewith the tumblers; Fig. 10 is a section through line In the preferredembodiment of my in- '.vention,-. I provide a suitable casing, as 1,

iwhichhas suitable flanges, as 2 and 3, for securing the casingto a door or the like. Within the casing 1 is located a framework 4:which is held in-place by means of lugs 5 and 6': adapted to fit into any suitable openings in the casing. 1, and by the rear plate 7, which is secured to the casing by suitable means; as screws 8. The framework 4 has fanyfnumber of'uprights 9-9, which are prolvidedxwith apertures 10, in which the teeth ill onthe tumblers 12 reciprocate.

, Each of the tumblers 12 is so formed as to have av general cylindrical contour and is providedw'ith: a flattened surface, as 18, and a'series of'teeth as 11,which form guides forthe'same in its reciprocatory movement.

VV-ith; theseand other objects in view the" The teeth 11 slide in the aperture 10 while the flat surface 13 impinges against the rear plate 7, and thus the tumbler 12 is held in proper relation to the uprights 9. I have shown only two tumblers and operating means for the same, but it will be evident that it is Within the scope of this invention to use any number of tumblers that may be desired, in order to give a wider range of combination. The tumblers 12 are preferably constructed with a bolt or rounded portion 14, having secured thereto a flange or projection 15 upon which the teeth 11 are formed. Mounted upon the cylindrical portion 14 are any suitable number of plates 16 which are adapted to fit snugly around the portion 14 and the flange or projection 15 and may be removed and rearranged as may be desired. By thus providing the tumbler 12 with a number of plates 16, the notch 17 formed by cutting away a portion of one of the plates 16 may be varied so as to change the combination. After a suflicient number of plates 16 have been placed upon the portion 14 a suitable nut or other securing means is mounted upon the end thereof for holding the same in place.

Secured to the uprights 9 are suitable brackets 18 which carry a shaft 19 on which is mounted a suitable number of operating levers for bringing the tumblers 12 into operative position and then for moving the same from said position. Each of the operating means with its tumbler is identical with all others, and, therefore, it will be sufficient to only describe one of the same in order to give the idea of the complete lock. A lever 20 is mounted upon the shaft 19 and is operated by means of a suitable operating means 21, located on the outside of the lock. Pivotally connected to the inner end of the lever 20 is a reciprocating bar 22 which is provided with a catch or projection 23, the catch being adapted to normally project into the aperture 10 of the upright 9 in the path of the teeth of the tumbler 12 and engage one of the same. The bar 22 is formed with a cut-away portion 23 which is adapted to accommodate the outer end of a cross-bar 24 which is adapted to hold the bar 22 in such a position as to disengage the catch or projection 23 from the teeth of the tumbler 12 when it is desired to move the tumbler 12 out of operative position. As will be clearly seen from Fig. 4 when the outer end of the lever 20 is depressed, the bar 22 through the medium of the catch 23 will raise the tumbler 12, the cut-away portion 23 permitting the reciprocation of the bar 22, While the cross-bar 24 is permitted to remain in an inoperative position.

Secured to the uprights 9, near one end thereof is a bracket 25 upon which are pivotally mounted bars 26 which extend to and rest upon the cross-bar 24 near the ends the bar 22. This particular position of the catch 27 is necessary in order that when the bar 22 is reciprocated and the tumblers 12 are elevated by the raising of the projection or catch 23 means will be provided for holding the same in its elevated position during the return movement of the bar 22. In order to hold the bar 26 and its catch 27 in operative position a spring 28 is mounted upon a shaft 29 one end of which impinges against a lug 30 formed integral with or secured to the bar 26. In order to hold the bar 22 in its operative position a spring, as 31, is secured to the shaft 32 forming a pivotal bearing for the bar 22 one end of which impinges upon a projection 33 secured to or formed integral with the bar 22. By the use of the springs 28 and 31 the catches 23 and 27 are normally held in their operative positions. Secured to or formed integral with the lever 20 is an arm 34- to one end of which a spring is secured thereto, the other end of the spring being fastened to a fixed part of the casing. This arrangement is provided for normally holding the outer end of the lever 20 in an elevated position. The bracket 25 is formed with a vertical portion 36 which is provided with a suitable aperture through which the knob shaft 37 projects. On the outer end of the knob shaft 37 is provided any suitable form of knob 38, while on the inner end of the shaft 37 is positioned a tumbler engaging bar 39 which is preferably beveled at 40 and 41 for permitting the tumblers 12 acting against the beveled surfaces to assist the spring 42 in forcing the tumbler engaging bar 39 out of engagement with the notched portion 17. The tumbler engaging bar 39 is pivotally mounted upon the shaft 37 and will consequently permit the said shaft to revolve without in any way moving the bar 39. The bar 39 is adapted to engage, when in operative position, the notches 17 in the tumblers 12, and when so engaging the notches 17, the shaft 37 will be in such a position as to permit a depending arm 43 to engage the bolt 44 for operating the same. The bolt 44 is normally held in its locked or outer position by a spring 45 and when it has been rc tracted by means of the projection 43, said bolt will immediately be forced by the spring 45 to its outer position after the operator releases knob 38. Immediately upon the releasing of the knob 38 the projection 43 is permitted, a partial rotation until the lllfi analo s-:1

samecome's opposite-cut away portion-47 when arm 43, together with shafti37' is moved inwardlyvby; the action of spring a 42. From thisit will be seen that when the hand of'the operator is removed from the knob 38' the. shaft 37 will immediately be forced inward by the spring 42 carrying with it the I notch engaging bar 39. The rear-plate7 has a-cut-away portion 46through which the bar 39 may reciprocate and the walls of which hold the bar 39"always in position to be drawn forward to engage the notches 17 notches 17 in tumblers 12 have been raised to a position opposite the bar 39 and then the knob is grasped and pulled outward until thebar 39engages the notches *17. The

reciprocation of the shaft 37 in thisdirection permits the depending arm- 43 to engage the bolt 44 for operating the same. When the notches17 are in alinement and the depending arm 43 is permittedto engage the bolt i4the-same may beoperated as often as desired,- but immediately upon releasing the knob 38 the shaft 37 carrying'the depending arm 43 willbe-forced rearward, and consequently the depending armwill be removedfrom engagement with the bolt 44. As long as thetumblers are in such a" position as-to have'the notches 17 in alinement the bolt or knob shaft 37 i carrying with it the depending arm 43-may bereciprocated as often as desired, but when any oneor all of the tumblers 12 aremovedso as to move one or all of the notches 17 V out ofalinement the shaft 37 cannot be reciprocated and, therefore, the depending arm 43 cannot be brought-intoengagement with the bolt 44. In order to prevent any damage or mischief being done to the mechanism of the lock the bracket 25 has acutaway portion 47 which is adapted to-receiveJ-the arm 43 when the same is in its inner position. The arm 43 is rigidly secured to the shaft 37, and consequently when it is in engagement with the bracket 25, the shaft 37 cannot be revolved because of bracket 25 or reciprocated because oftumblers 12.

When the tumblers 12 have their notches 17 in alinement and it is desired to change the combination an operating member 48 is depressed which in turn operates a'lever 49. When the outer end of the lever 49 is depressed the inner end will raise a reciprocating member 50 which is formed with beveled portions 5].51. WVhen the reciprocating member 50 is raised the beveled sur-.

faces 51 will act against the cross-bar 24 and raise or move the same at right angles to the uprights 9; When the bar 24 is thus raised or moved-jit carries with it the bars 22 and 26 with their respective catches.

Thus it will be seen when the lever 49 is-depressed the catches 23 and 27 are disengaged from the teeth 11, and will permit the tumblers12 to drop by gravity to their lowermost: position against the end of the frame 4. Of course, in order to move the tumblers 12 to their lowermost position,

not only the catches 23 and 27 must be disengaged, but also the bar 39. As above described-the bar 39-is normally held by the spring. 42 out of engagement with the tumblers12, and, therefore, any time that it is desired to change the combination, it is simply necessary to depress the operating member 48 once and-all the tumblers will be forced to their lowermost position.

Aswill be seen from'Figr 6 the notch 17 is positioned at a different place upon the tumblers 12 to their lowermost position,

necessary inbringing the tumblers into operative. position, that 1s the notches. into almement, to depress one of the operating means 21 one more time than the other. It

will be evident that it is within the spirit of this invention that the notches 17 may be placed at any point along the tumblers 12 which is rigidly secured to the bolt 44 and reciprocateswiththe same. A person desiring. to operate the bolt from the inside may do so by simply. reciprocating the lug 54. \Vhen. it is desired to hold the bolt44 either in vits outer or inner position a reciprocating member 55 which is mounted upon the plate '7, is adapted to have one end thereof moved within the path of travel of the lug 54, so thatwhen the member 55 is so positioned as'to be in the path of movement ofthelug 54, thesame cannotbe moved and consequently no one can operate the bolt 44 from .the. outside even if they are familiar with the combination. WVhen it is desired to allow the combination to be used the member 55 is raised and moved to one side and is held in that position by means of a lug 56 engaging the cut-out portion 57 in the member 55. While in this position the bolt 44 may be operated from the inside or from the outside by any one knowing the combination.

Havin thus fully described my invention, what I c aim as new and desire to secure by Letters Patent is 1. r A combination lock comprising a bolt, a reciprocating and rotating knob shaft, means secured to said shaft for operating said bolt,
